- 中文摘要: Coordination of a bulky pyridinyl-phosphine (P~N) ligand toward CuBr was investigated. However, this P~N donor behaves as a monodentate via the coordination of phosphine to form a bromide bridged dimeric [(P~N)Cu(m-Br)2Cu(P~N)], which was characterized by spectral and crystal structural analysis. It appeared that the “PCu(m-Br)2CuP” unit is planar with a short distance between Cu...Cu’ [2.7585(9) A]. The catalytic activity on Sonogashira coupling of phenylacetylene with aryl halides was studied.
